Error on challenge or am I missing something?

I'm asked to create a variable named numWidth. I set the variable with

var numWidth = boxWidth.parseInt();

but the challenge is telling me I don't have a variable named numWidth and that I should set it with "var numWidth =...".

Clearly this is an error on the challenge, right?

The instructions probably should say function not method.

parseInt is a function that you call and pass in arguments.

var numWidth = parseInt(boxWidth, 10);
